Description

本発明は、ミストの中にナノバブル（超微細気泡）を内蔵させてミストを高速噴射させるジェット噴射装置に関する。   The present invention relates to a jet injection device that incorporates nanobubbles (ultrafine bubbles) in mist to inject mist at high speed.

マイクロバブル（微細気泡）は、普通の泡よりもとても小さな気泡であるが、大きい泡に無いような様々な特長の、水中の浮上速度が極めて遅い、水に拡がり易い、水中の物質に吸着する、泡が壊れにくい等を備えることが分かっている。そのため、排水処理分野、洗浄分野、美容分野、養殖分野等の各方面にマイクロバブルの活用例が広がっている。
このマイクロバブルよりさらに小さな超微細気泡をナノバブルと称している。 Microbubbles (fine bubbles) are very small bubbles than ordinary bubbles, but they have various characteristics that are not found in large bubbles. It has been found that the foam is difficult to break. For this reason, examples of utilizing microbubbles are spreading in various fields such as the wastewater treatment field, the cleaning field, the beauty field, and the aquaculture field.
Ultrafine bubbles smaller than these microbubbles are called nanobubbles.

高圧液体と高圧空気とを混合させてジェット流を作り出し、先端ノズルから高速・高圧な混合流体を吹き付ける気液混合チーズが知られている（特開２０１３−１８４１５２号公報を参照）。
この特開２０１３−１８４１５２号公報は、チーズ本体５の上流側から水などの高圧液体が供給され、高圧空気配管１２から金属粒や砂粒などの研磨剤を含む高圧空気が供給されて中コマ８の位置で合流され、前記中コマ８の傾斜切り口７により４０〜５０°の角度で下流側の高圧流体へ合流され、高速・高圧な気液混合流体となって圧送される。
そのため、前記気液混合流体は、研磨対象物に付いた汚れや塗料などに高速のジェット流で衝突して汚れや塗料を剥ぎ取ることができる。 Gas-liquid mixed cheese is known in which a high-pressure liquid and high-pressure air are mixed to create a jet flow, and a high-speed and high-pressure mixed fluid is sprayed from a tip nozzle (see JP 2013-184152 A).
In JP 2013-184152 A, a high-pressure liquid such as water is supplied from the upstream side of the cheese body 5, and high-pressure air containing a polishing agent such as metal particles and sand particles is supplied from the high-pressure air pipe 12. Are joined to the high-pressure fluid on the downstream side at an angle of 40 to 50 ° by the inclined cut edge 7 of the middle piece 8 and pumped as a high-speed and high-pressure gas-liquid mixed fluid.
Therefore, the gas-liquid mixed fluid can peel off dirt and paint by colliding with dirt and paint on the object to be polished by a high-speed jet flow.

また、使用する装備が極めて少なく、ポンプと２流体ノズル、バルブ２個にポーラスフィルター及びチューブ類からなるマイクロバブル発生装置が知られている（特開２０１６−１１２４７７号公報を参照）。
この特開２０１６−１１２４７７号公報においては、ガス発生装置３からの気体と貯留槽１からの戻り液体を混合して気液混合流体を形成する２流体ノズル１１は、ノズル外筒１７にノズル嘴１８が嵌合し、ノズル外筒１７のノズル室１９のテーパー面にノズル嘴１８の先端が位置しており、循環チューブ１０からの戻り液体１が強く流れることで第一バルブ９への気体の吸引力が発生する。その時、ノズル室１９内では適度に液体と空気及びガス類が混じり合い、気液混合流体が形成される。加圧液体ポンプ１２から押し出される気液混合流体は、圧送チューブ１３に入り、定常状態に戻して過飽和状態になる時、強くキャビテーション（泡の発生と消滅現象）を発生し、溶存空気及びガス類が析出する。その際、気液混合流体は沸騰する。そのまま第二バルブ１４により適度なクリアランスに導かれて常圧に戻されるので、液体に溶け込んでいた気体はナノバブル（超微細気泡）となって貯留槽２に出る。 Also, there are very few equipments to be used, and a microbubble generator comprising a pump, a two-fluid nozzle, two valves and a porous filter and tubes is known (see Japanese Patent Application Laid-Open No. 2016-112477).
In this Japanese Unexamined Patent Application Publication No. 2016-112477, a two-fluid nozzle 11 that forms a gas-liquid mixed fluid by mixing the gas from the gas generator 3 and the return liquid from the storage tank 1 is connected to the nozzle outer cylinder 17 with a nozzle soot. 18 is fitted, and the tip of the nozzle rod 18 is positioned on the tapered surface of the nozzle chamber 19 of the nozzle outer cylinder 17, and the return liquid 1 from the circulation tube 10 flows strongly, so that the gas to the first valve 9 flows. A suction force is generated. At that time, in the nozzle chamber 19, the liquid, air, and gases are appropriately mixed to form a gas-liquid mixed fluid. When the gas-liquid mixed fluid pushed out from the pressurized liquid pump 12 enters the pressure feed tube 13 and returns to a steady state and becomes a supersaturated state, it strongly generates cavitation (bubble generation and disappearance phenomenon), and dissolved air and gases. Precipitates. At that time, the gas-liquid mixed fluid boils. As it is guided to a proper clearance by the second valve 14 and returned to the normal pressure, the gas dissolved in the liquid becomes nanobubbles (ultrafine bubbles) and exits to the storage tank 2.

前述した公知技術は、それぞれジェット流およびマイクロバブルの発生装置であり、個々の発明である。本出願人はこれら技術を関連結合し、ミストにナノバブルを内蔵させて高速噴射することにより、ミストに内蔵させているガスの種類に依存した効果を発揮できることを実証した。   The above-described known techniques are jet flow and microbubble generators, and are individual inventions. The present applicant has demonstrated that an effect depending on the type of gas incorporated in the mist can be exerted by combining these technologies in association with each other and by incorporating nanobubbles in the mist and performing high-speed injection.

特開２０１３−１８４１５２号公報（図１を参照）JP 2013-184152 A (refer to FIG. 1) 特開２０１６−１１２４７７号公報JP 2016-112477 A

本発明は、ミストの中にナノバブル（超微細気泡）を内蔵させてミストを高速噴射させるジェット噴射装置を提供することを目的とする。   An object of the present invention is to provide a jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist to inject the mist at a high speed.

本発明のジェット噴射装置は、円筒管のノズル外筒と該ノズル外筒に直角に一体接続されたエアー接続管とからなる２流体ノズルと、該２流体ノズルのノズル外筒に高圧のナノバブル水を供給するナノバブル発生装置と、前記２流体ノズルのエアー接続管に高圧空気を供給するコンプレッサーとから構成されてなる。   The jet injection device according to the present invention includes a two-fluid nozzle including a nozzle outer cylinder of a cylindrical tube and an air connection pipe integrally connected to the nozzle outer cylinder at a right angle, and high-pressure nanobubble water in the nozzle outer cylinder of the two-fluid nozzle. And a compressor for supplying high-pressure air to the air connection pipe of the two-fluid nozzle.

本発明のジェット噴射装置の一実施例を添付図面に基づいて、以下に説明する。
図１の概略説明図に示すように、本発明のジェット噴射装置は、円筒管のノズル外筒１と該ノズル外筒１に直角に一体接続されたエアー接続管２とから構成されてなる２流体ノズル３と、前記２流体ノズル３の一方のノズル外筒１に高圧のナノバブル水を供給するナノバブル発生装置４と、前記２流体ノズル３の他方のエアー接続管２に高圧空気を供給するコンプレッサー５とからなる。 An embodiment of the jet injection device of the present invention will be described below with reference to the accompanying drawings.
As shown in the schematic explanatory diagram of FIG. 1, the jet injection device of the present invention comprises a nozzle outer cylinder 1 of a cylindrical pipe and an air connection pipe 2 integrally connected to the nozzle outer cylinder 1 at a right angle. A fluid nozzle 3, a nanobubble generator 4 that supplies high-pressure nanobubble water to one nozzle outer cylinder 1 of the two-fluid nozzle 3, and a compressor that supplies high-pressure air to the other air connection pipe 2 of the two-fluid nozzle 3 It consists of five.

前記２流体ノズル３は、図２の説明図及び図３の断面図に示すように、金属製や合成樹脂製の円筒管のノズル外筒１を設け、該ノズル外筒１に直角にエアー接続管２が一体に接合される。
そして、前記ノズル外筒１の下流側先端部に小径筒孔６を備えたノズル嘴７を接続し、さらに前記ノズル嘴７を囲むようにノズル筒８を接続する。
前記ノズル筒８は、前記ノズル嘴７を収納する大径のノズル室９を備え、該ノズル室９から縮径となるようにテーパー面１０を形成し、該テーパー面１０から引き続き前記ノズル嘴７の小径筒孔６より大径の大径筒孔１１を形成する。前記ノズル嘴７先端を前記テーパー面１０に接近させて配置する。
前記ノズル筒８のノズル室９に外気と連通するようにノズル筒９外周に空気吸引孔１２を設ける。
また、前記ノズル外筒１の上流側先端部には、第一バルブ１３を介して高圧流体配管１４が接続されて圧縮水、本実施例では高圧のナノバブル水が供給される。
前記エアー接続管２には、第二バルブ１５を介して高圧空気配管１６が接続されて圧縮空気が供給される。 As shown in the explanatory diagram of FIG. 2 and the sectional view of FIG. 3, the two-fluid nozzle 3 is provided with a nozzle outer cylinder 1 of a cylindrical tube made of metal or synthetic resin, and is connected to the nozzle outer cylinder 1 by air connection at a right angle. Tube 2 is joined together.
A nozzle rod 7 having a small-diameter cylindrical hole 6 is connected to the downstream end portion of the nozzle outer tube 1, and a nozzle tube 8 is connected so as to surround the nozzle rod 7.
The nozzle cylinder 8 includes a large-diameter nozzle chamber 9 that accommodates the nozzle rod 7, a tapered surface 10 is formed so as to have a diameter reduced from the nozzle chamber 9, and the nozzle rod 7 continues from the tapered surface 10. A large-diameter cylindrical hole 11 having a larger diameter than the small-diameter cylindrical hole 6 is formed. The tip of the nozzle rod 7 is disposed close to the tapered surface 10.
An air suction hole 12 is provided on the outer periphery of the nozzle cylinder 9 so as to communicate with the outside air in the nozzle chamber 9 of the nozzle cylinder 8.
A high-pressure fluid pipe 14 is connected to the upstream end of the nozzle outer cylinder 1 via a first valve 13 to supply compressed water, in this embodiment, high-pressure nanobubble water.
A high-pressure air pipe 16 is connected to the air connection pipe 2 via a second valve 15 to supply compressed air.

気相・液相の２流体ノズル３では、空気圧により液の圧力が回復され、空気と液の密度差が出てノズル嘴７に導かれる。ノズル嘴７ではベルヌーイの定理により流速に応じた負圧が発生する。その負圧により、ミストの粒子径１０μｍから１５０μｍまでの粒子が発生する。平均粒子径は５０μｍである。
ミストの粒子径は圧縮空気の量により可変させられるので、好みの粒子径を得るには手元の第二バルブ１５の可変で行える。
ノズル筒８の大径筒孔１１は４ｍｍ以上で使用するが、ポンプ能力により大きい口径も使用できる。
ミストの飛距離は液体圧力３ｋｇで空気圧０．７ＭＰａにおいて地上高１ｍで１２ｍ〜１５ｍである。
ミスト中にナノバブル粒子を混合させて吹くが、ナノバブル中にガス類を入れることにより、途中蒸発することなく対象物に衝突させてその効果を得ることができる。ミストのみでは２０μｍ以下では蒸発するスピードが速く効果は限定的であるが、ナノバブルを入れたミストでは性質的に蒸発し難いので効果は長く期待できる。 In the gas-phase / liquid-phase two-fluid nozzle 3, the pressure of the liquid is recovered by the air pressure, and the density difference between the air and the liquid is generated and guided to the nozzle 7. In the nozzle rod 7, a negative pressure corresponding to the flow velocity is generated by Bernoulli's theorem. Due to the negative pressure, particles having a mist particle size of 10 μm to 150 μm are generated. The average particle size is 50 μm.
Since the particle diameter of the mist can be varied depending on the amount of compressed air, the desired second particle diameter can be varied by using the second valve 15 at hand.
The large-diameter cylindrical hole 11 of the nozzle cylinder 8 is used at 4 mm or more, but a larger diameter can also be used for the pump capacity.
The flying distance of the mist is 12 to 15 m at a ground height of 1 m at a liquid pressure of 3 kg and an air pressure of 0.7 MPa.
The nanobubble particles are mixed and blown into the mist, but by putting gases into the nanobubbles, the effect can be obtained by colliding with the object without evaporating halfway. If the mist alone is 20 μm or less, the evaporation speed is fast and the effect is limited. However, since the mist containing nanobubbles is difficult to evaporate in nature, the effect can be expected to be long.

図４の概略説明図に示すように、前記ナノバブル発生装置４は、ボックス１７内にダイヤフラム式バブル発生機１８とダイヤフラムポンプ１９を設置する。
前記ダイヤフラム式バブル発生機１８には、ＣＯ２などの各種ガス入りのガスタンク２０を接続すると共に貯水タンク２１の貯留水を接続し、前記ダイヤフラム式バブル発生機１８により生成されたナノバブル気泡を貯水タンク２１に貯留する。ダイヤフラム式バブル発生機１８のナノバブル粒子量は１ｍｍｌあたり１．５×１０８個である。なお、各種ガス入りナノバブル気泡は貯水タンク２１内で長期保存され、直ぐに消滅することはない。
前記ダイヤフラムポンプ１９には、一方から前記貯水タンク２１の各種ガス入りバブル水を引き込み、他方からコンプレッサー５からの圧縮空気を取り込む。
前記ダイヤフラムポンプ１９により各種ガス入りバブル水と圧縮空気とが気液混合状態となり、高圧となったナノバブル水が下流側の高圧液体配管１４へ送られる。 As shown in the schematic explanatory diagram of FIG. 4, the nanobubble generator 4 has a diaphragm bubble generator 18 and a diaphragm pump 19 installed in a box 17.
The diaphragm-type bubble generator 18 is connected to a gas tank 20 containing various gases such as CO 2 and is connected to water stored in a water storage tank 21, and the nanobubble bubbles generated by the diaphragm-type bubble generator 18 are stored in the water storage tank 21. Store in. The amount of nanobubble particles in the diaphragm bubble generator 18 is 1.5 × 10 8 per 1 ml. In addition, nanobubble bubbles containing various gases are stored for a long time in the water storage tank 21 and do not disappear immediately.
The diaphragm pump 19 draws bubble water containing various gases from the water storage tank 21 from one side, and takes in compressed air from the compressor 5 from the other side.
Various diaphragms containing gas and compressed air are brought into a gas-liquid mixed state by the diaphragm pump 19, and high-pressure nanobubble water is sent to the high-pressure liquid pipe 14 on the downstream side.

図５の原理説明図に示すように、前記ナノバブル発生装置４は、貯水タンク２１の液体を２流体ノズル２２に圧送し、前記２流体ノズル２２内では、図６の断面図に示すように、各種ガス吸引口２３からガスバルブ２４を介して高圧ガスが送られ、一方矢印で示す高圧液体の流速によりテーパー面２５の負圧発生空間に発生する負圧により高圧液体と高圧ガスが混合され、気液混合状態の旋回流のミストとなって下流へ送られる。
図５に示すダイヤフラムポンプ１９によって断続的に高圧の気液混合流体となってフレキシブル管２６へ送られ、該フレキシブル管２６内で定常状態に戻して過飽和状態になる時に強くキャビテーション（泡が発生し消滅する現象）を発生し、溶存ガスを析出し、気液混合流体は沸騰する。
そのままで送られ、縦型のＴ型チーズ２７の空気抜き弁２８により適度なクリアランスに導かれて常圧に戻されるので、溶け込んでいた気体はナノバブル気泡となって横型のＴ型チーズ２９、チューブ３０、減圧弁３１を経て貯水タンク２１内へ導かれる。
なお、横型のＴ型チーズ２９には、圧力測定のために圧力メータ３２を接続する。 As shown in the principle explanatory diagram of FIG. 5, the nanobubble generator 4 pumps the liquid in the water storage tank 21 to the two-fluid nozzle 22, and in the two-fluid nozzle 22, as shown in the cross-sectional view of FIG. 6, High pressure gas is sent from the various gas suction ports 23 through the gas valve 24, and the high pressure liquid and the high pressure gas are mixed by the negative pressure generated in the negative pressure generation space of the tapered surface 25 by the flow velocity of the high pressure liquid indicated by an arrow. It is sent downstream as a mist of a swirling flow in a liquid mixed state.
The diaphragm pump 19 shown in FIG. 5 intermittently becomes a high-pressure gas-liquid mixed fluid and is sent to the flexible tube 26. When the state is returned to a steady state and becomes supersaturated in the flexible tube 26, cavitation (bubbles are generated strongly). (Disappearing phenomenon) occurs, the dissolved gas is deposited, and the gas-liquid mixed fluid boils.
Since it is sent as it is and is led to an appropriate clearance by the air vent valve 28 of the vertical T-type cheese 27 and returned to normal pressure, the dissolved gas becomes nanobubble bubbles, and the horizontal T-type cheese 29 and the tube 30 Then, the water is introduced into the water storage tank 21 through the pressure reducing valve 31.
A pressure meter 32 is connected to the horizontal T-type cheese 29 for pressure measurement.

次に、本発明のジェット噴射装置の操作動作を添付図面に基づいて、以下に説明する。
図１に示すように、ガスタンク２０内の高圧ガス、例えばＣＯ２ガスがレギュレータ３３を介して図４に示すダイヤフラム式バブル発生機１８に圧送され、他方、貯水タンク２１内の貯留水が同様に前記ダイヤフラム式バブル発生機１８に圧送される。
前記ダイヤフラム式バブル発生機１８では、図５に示す原理でナノバブル水が発生され、貯水タンク２１内にＣＯ２ナノバブル水が貯留される。
ダイヤフラムポンプ１９によりＣＯ２バブル水と圧縮空気とが気液混合状態となり、高圧となったナノバブル水が下流側の高圧液体配管１４へ送られる。 Next, the operation of the jet injection device of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, a high-pressure gas in the gas tank 20, for example, CO 2 gas, is pumped to the diaphragm bubble generator 18 shown in FIG. 4 through the regulator 33, while the stored water in the water storage tank 21 is similarly It is pumped to the diaphragm type bubble generator 18.
In the diaphragm type bubble generator 18, nanobubble water is generated based on the principle shown in FIG. 5, and CO 2 nanobubble water is stored in the water storage tank 21.
The diaphragm pump 19 causes the CO2 bubble water and the compressed air to be in a gas-liquid mixed state, and the high pressure nanobubble water is sent to the high pressure liquid pipe 14 on the downstream side.

図１に示す２流体ノズル３には、高圧液体配管１４から第一バルブ１３を介して圧縮水、すなわちナノバブル水が圧送され、またコンプレッサー５により高圧空気配管１６から第二バルブ１５を介して圧縮空気が送られる。
図３に示す直管のノズル外筒１に前記ナノバブル水が圧送されると共にエアー接続管２から圧縮空気が圧送されるので、合流点で気液混合され、気液混合流体となってノズル嘴７へ流出する。
前記ノズル嘴７は、ノズル室９のテーパー面１０に接近しているので、ノズル嘴７先端に負圧が発生し、空気吸引孔１２から外気を導入し、外気が気液混合流体と合流して気液混合状態の旋回流のミストとなって下流へ送られ、ノズル筒８の先端部からナノバブルを内蔵したミストとなって高速噴射される。 Compressed water, that is, nanobubble water is pumped from the high-pressure liquid pipe 14 through the first valve 13 to the two-fluid nozzle 3 shown in FIG. 1 and compressed by the compressor 5 from the high-pressure air pipe 16 through the second valve 15. Air is sent.
Since the nano bubble water is pumped to the straight nozzle outer cylinder 1 shown in FIG. 3 and compressed air is pumped from the air connection pipe 2, it is gas-liquid mixed at the confluence to become a gas-liquid mixed fluid. To 7
Since the nozzle rod 7 is close to the tapered surface 10 of the nozzle chamber 9, a negative pressure is generated at the tip of the nozzle rod 7, the outside air is introduced from the air suction hole 12, and the outside air merges with the gas-liquid mixed fluid. As a result, the swirl flow mist in a gas-liquid mixed state is sent downstream, and the mist containing nanobubbles is ejected from the tip of the nozzle cylinder 8 at a high speed.

本発明は、吹き付けるミスト内にナノバブル粒子を内蔵させることが最大の特徴であり、内蔵させているガスの種類に依存した効果を発揮できる。
ミストのみを１０μｍ以下にすると大気中に蒸発してしまうが、ナノバブルを内蔵させることで蒸発しにくくなり、マイナスに強く帯電することで到達後被射体に対してマイナス荷電効果と、内蔵するガス効果が得られる。 The greatest feature of the present invention is that the nanobubble particles are incorporated in the sprayed mist, and an effect depending on the type of the incorporated gas can be exhibited.
If only mist is reduced to 10 μm or less, it will evaporate in the atmosphere. However, by incorporating nanobubbles, it will be difficult to evaporate. An effect is obtained.

農業分野では、ＣＯ２ガス内蔵のナノバブルを内蔵したミストを吹き付けると、真性菌や細菌類等に対して、静菌効果や抗菌効果が得られることは確認されている。また日中においては植物の光合成効果を助けるので、太陽エネルギーの貯蔵（澱粉製造）に対する効果も期待できる。
ハウス内における従来の生ガス封入は人畜に対するガス中毒の危険性も指摘されるが、本発明のミスト内ガスの封入と散布は目に見える形であるため、ガス濃度に対する危険は少ない。
植物には、葉にも根にもナノバブル水化は吸収に貢献するので、便利である。その場合に、根には酸素水をかけ、葉にはＣＯ２水をかけることで生育に貢献する。 In the agricultural field, it has been confirmed that bacteriostatic and antibacterial effects can be obtained against eubacteria and bacteria by spraying mist containing nanobubbles containing CO2 gas. Moreover, since it helps the plant's photosynthesis effect in the daytime, it can also be expected to have an effect on solar energy storage (starch production).
Although it is pointed out that there is a risk of gas poisoning of human livestock in the conventional live gas filling in the house, the risk of gas concentration is small because the filling and spraying of the gas in the mist of the present invention is visible.
For plants, hydration of nanobubbles in both leaves and roots contributes to absorption, which is convenient. In that case, oxygen water is applied to the roots and CO2 water is applied to the leaves to contribute to growth.

航空機の塩害除去に対して、ミスト内にナノバブル粒子を内蔵することで被射体に対するガスの効果と水による流す効果と、ミスト全体がマイナスに帯電する効果が得られる。これらは従来の高圧洗浄機にはない効果である。
生ガスを１０ｍ以上飛ばす装置はないが、ミストでは容易に飛ぶので便利である。
ミストに内蔵されるナノバブルは十分な高圧に変化しており、装置内の圧力では壊れない。
一旦製造したガス入りナノバブルは数ヶ月間持つので、作り置きが可能であり、タンク内に前もって作っておくことで使用できるので、便利である。 For removing salt damage from aircraft, by incorporating nanobubble particles in the mist, the effect of gas on the subject, the effect of flowing with water, and the effect of negatively charging the entire mist are obtained. These are effects not found in conventional high-pressure washing machines.
There is no device for flying raw gas more than 10m, but it is convenient because it can fly easily with mist.
The nanobubbles contained in the mist are changed to a sufficiently high pressure and are not broken by the pressure in the apparatus.
Once produced, nanobubbles with gas will last for several months, so they can be made and can be used by making them in advance in a tank, which is convenient.

上述したように、本発明のジェット噴射装置は、多用途に利用できるが、ほかに下記の用途にも使用できる。
１．洗浄装置
・洗浄装置として液の使用が高圧洗浄機の約半分で済む。
・ノズルの先端が解放型（絞りがない）なので詰まりなどがない。
・ミスト流速はノズル先端でマッハ１であり、ミスト群は飛散することなく目的物に
吹き付けられる。水の固まりが飛ぶのではなく、一粒ずつが完全な粒子径として飛
ぶので洗浄効果が高い。
２．消火装置
・ＣＯ２ガスを目的地まで吹き付けガスの遮断効果を期待できる。
３．船の推進器
・推進器として使用すると反作用効果により高出力の推進が得られる。
４．バブル風呂 As described above, the jet injection device of the present invention can be used for many purposes, but can also be used for the following purposes.
1. Cleaning device-About half of the high-pressure cleaning machine can be used as a cleaning device.
・ No clogging because the tip of the nozzle is an open type (no iris).
-The mist flow rate is Mach 1 at the nozzle tip, and the mist group is sprayed onto the object without scattering. Rather than a lump of water flying, each particle will fly as a complete particle size, so the cleaning effect is high.
2. Fire extinguisher ・ CO2 gas can be blown to the destination and gas blocking effect can be expected.
3. Ship propulsion device ・ When used as a propulsion device, high output propulsion is obtained due to the reaction effect.
